Usage examples

For a full documentation please check DynamicsWebApi on GitHub.

Dynamics 365 Web Resource

To use DynamicsWebApi inside Dynamics 365 you need to download a browser version of the library, it can be found in v2 dist folder.

Upload a script as a JavaScript Web Resource, add it to a table form or reference it in your HTML Web Resource and then initialize the main object:

//By default DynamicsWebApi makes calls to 
//Web API v9.2 and Search API v1.0
const dynamicsWebApi = new DynamicsWebApi();

const response = await dynamicsWebApi.callFunction("WhoAmI");
Xrm.Navigation.openAlertDialog({ text: `Hello Dynamics 365! My id is: ${response.UserId}` });

Microsoft Power Pages (Microsoft Portal)


There are two ways to include DynamicsWebApi in your portal: upload as a Web File or use CDN, such as unpkg.

It is possible to upload the library as a Web File in Microsoft Power Pages. Usually, the .js extensions are forbidden to upload but it is still possible to do, here's a workaround.

Once the web file is uploaded, it can be included in a template, a page or a form the following way:

<script type="text/javascript" src="~/dynamicsWebApi.min.js"></script>

With CDN, it is a bit easier: no need to create and upload a web file - just include the script in your template, page or a form:

<script type="text/javascript" src="https://unpkg.com/dynamics-web-api@2.1.0/dist/dynamics-web-api.min.js"></script>

And you are good to go! DynamicsWebApi will automatically detect if the library is running on Power Pages and will supply an anti-forgery token with each request.


To use DynamicsWebApi in Node.js install the dynamics-web-api package from NPM:

npm install dynamics-web-api --save

Then include it in your script:

const DynamicsWebApi = require("dynamics-web-api");

import { DynamicsWebApi } from "dynamics-web-api";

Example of a Batch Operation using DynamicsWebApi

const contact = {
    firstname: "John",
    lastname: "Doe"

const order = {
    name: "1 year membership",
    //reference a request in a navigation property
    "customerid_contact@odata.bind": "$1"

dynamicsWebApi.create({ data: contact, collection: "contacts", contentId: "1" });
dynamicsWebApi.create({ data: order, collection: "salesorders" });

const responses = await dynamicsWebApi.executeBatch();

//in this case both ids exist in a response
//which makes it a preferred method
const contactId = responses[0];
const salesorderId = responses[1];
